A prospective study of 40 patients with cancer of the oesophage or cardia considered for surgery showed that 27 had no evidence of protein or calorie deficiency, while 13 had undernutrition. The 18 patients who benefited from ablative surgery belonged to the group with normal nutritional status; none of the undernourished patients could have benefited from resection. Only controlled studies will show whether or not correcting undernutrition is advantageous, but the number of people with both resectable tumour and corrigible undernutrition is probably very small.
一项针对40例考虑手术治疗的食管癌或贲门癌患者的前瞻性研究表明，27例患者没有蛋白质或热量缺乏的证据，而13例存在营养不良。18例从切除手术中获益的患者属于营养状况正常的组；营养不良的患者无一能从切除术中获益。只有对照研究才能表明纠正营养不良是否有益，但同时患有可切除肿瘤和可纠正营养不良的人数可能非常少。
